While trying to remove recurrence of events, I accidentally deleted the meeting requests (sent by others) and canceled the ones (created by me).
I want to recover those items. How can I do that?
All deleted items should be in your Deleted items
folder under Inbox
or if you've deleted them from deleted items, they should be available for restoration under Tools
->Recover Deleted Items
for some time.
You might find this guide and this guide useful. Oh! and this one as well.
Edit:
Actually, restore deleted calendar got the same steps as restore deleted messages. You must be a Microsoft Exchange Server account.
1.In the folder from which the item was deleted, or in the Deleted Items folder, on the Folder tab, in the Clean Up group, click Recover Deleted Items. Note: If the Recover Deleted Items command is missing:
An Exchange account is required for this command to appear. If you are using an Exchange account and don’t see the command, contact your Exchange administrator.
2.Click an item, and then click Recover Selected Items . Note: Your Exchange administrator specifies the retention time for deleted items. After this time elapses, deleted items cannot be restored.

menu in case they were removed from Deleted Items. I belive mfcmapi tool would be able to find them if not visible in GUI.
